Do you really know?

Whether it’s in the street, on public transport or at home, almost all of us use headphones or earphones to listen to music. Now music might bring us joy and a whole lot of other emotions, but when it’s too loud, it can also represent a risk for hearing health. And it’s not just the case with personal listening devices; the same is also true when going to entertainment venues like nightclubs, bars...

You’re no doubt familiar with IKEA as the king of flatpack furniture. But you may not be aware that the Swedish company’s name is also associated with a cognitive bias. It’s all to do with how we assign greater value to objects when we make or assemble them ourselves. Now that might seem counterintuitive but it’s become an established marketing tactic over the years. Studies by American researcher...

Social science research is becoming more and more fruitful. As a result, an almost endless list of terms are emerging, like 'white privilege' or 'ageism’, which we have already covered in past episodes of Do You Really Know? These studies often share the same objective and that is to shine a light on social phenomena we tend to dismiss, calling out persisting discrimination. The words 'ableism' an...

Antibiotics are critical to modern medicine, and have saved millions of lives since first being introduced in the mid-20th century. However, there are drawbacks to prescribing antibiotics when they’re not actually required. Of course there’s the issue of antibiotic resistance, which is seen as a major threat to human health. And there are also unwanted side effects of antibiotic use to take into a...

Have you ever walked into your living room, kitchen or bedroom and completely forgotten what you went there for? It can be pretty annoying, and a little unsettling too. You might start wondering if you’ve got memory problems. This mental block phenomenon actually has a name: the doorway effect. It happens to most people from time to time. Through a series of studies run by Gabriel Radvansky and hi...

One of the consequences of the pandemic has been the increased interest and possibility for people to work from home. For many it is a great option, but increasingly employers are worried about time theft. Time theft is a catch all term for employees being paid for being at work when they were not really working. It could be because of things like taking longer breaks than scheduled; logging off e...

The ChatGPT AI chatbot has grabbed a lot of attention since it was released in December 2022. GPT stands for generative Pre-trained transformer, and the chatbot is based on one of the most advanced AI language models currently available. Those who’ve tested it have been impressed at how it generates complex, human-like responses to many different kinds of questions. It’s also been used to write es...

Online influencer and self-confessed misogynist Andrew Tate has now been in prison for over a month, following his arrest in late December on human trafficking charges. The Romanian police force who arrested him released a statement saying Tate, along with his brother and two other suspects, used “physical violence and mental coercion” to force victims to perform pornography. The statement went in...

Electric cars feel like a great choice for the environment but are they a great choice for you? Here are some tips and advice to help you decide. Despite the cost of electricity going up recently electric cars are still less expensive to run than petrol or diesel equivalents. When it comes to charging your car you will get the best price by charging at home on off-peak hours. Using a public charge...

When it comes to getting clean, some people prefer chilling in the bath for a good half an hour or more, while others like how quick and practical it is having a shower. Let’s consider the two choices from a health perspective. It's pretty common knowledge that taking a bath isn't very eco-friendly, in terms of water consumption. Of course there are variables at play here when comparing the two. W...

Data published by YouGov in August 2022 showed that as of the previous month, Britons were using a whopping £3.5bn worth of overdrafted funds from their bank accounts. Each month, between 25% and 30% of people dip into their overdrafts, generally just for a few days leading up to payday. It’s hardly surprising with the ongoing cost of living crisis and energy bills rising rapidly. If you’re one of...

The COP26 summit, which took place earlier this month, revealed that concerns related to climate change are now more pressing than ever. In June 2021, Madagascar became the first country in the world officially affected by a climate change famine that swept over the south of the island as a result of global warming. What makes it a particularly affected area is that 9 out of 10 people there live b...

It’s been labelled a “marvel of engineering” and a “miracle of convenience” by Harvard Health Publishing. Data published by Statista in July 2022 showed that in 2018, 93% of UK households owned a microwave, a figure which had risen from 67% when the survey started back in 1994. But still some doubts persist about whether microwaving food is bad for your health. Some people even say they cause canc...

We’ve talked about eco-anxiety before on Do You Really Know, and it’s real. A survey published in the Lancet in December 2021 found that 75% of young people thought the future was frightening. But others are preaching a more positive outlook, with cautious climate optimism looking set to be a trend in 2023. While our fears around the climate crisis are justified and useful, if they paralyse us out...

Most of us are familiar with the idea that you need to take 10 thousand steps per day to stay healthy but getting to this magic number is not that easy. The 10,000-step target first became popular in Japan in the 1960s. A clockmaker capitalising on people's new interest in fitness following the 1964 Tokyo Olympic Games made a  pedometer with a name that, when written in Japanese characters, resemb...

All week long, we’re looking into 10 new terms and concepts that are certain to be on everyone’s lips in 2023! Covid-19 restrictions changed work practices radically; a large proportion of the workforce have worked remotely for nearly three years now. That’s the case even in post-pandemic working structures, with many sectors favouring a hybrid model rather than a full-time return to the office. W...

Smart devices can be very handy, but increasingly people are worried about exactly how smart they are, what they know and what they are doing with our data especially after a rogue Roomba ended up sharing embarrassing photos of one young woman on the toilet. Smart devices are electronic devices or gadgets that have the ability to interact, connect and share information with other smart devices. It...

January 16th is Martin Luther King Day. In the United States, this is a federal holiday in the United States marking the birthday of Martin Luther King Jr. King was a key figure in the Civil Rights Movement, which protested racial discrimination in federal and state law. The fight against racial discrimination is still essential today.

All week long, we’re looking into 10 new terms and concepts that are certain to be on everyone’s lips in 2023! For a number of years now, we’ve been hearing that the future of transport is electric, in particular due to the impact of fossil fuels on global warming. But there are a number of drawbacks, including cost, battery life, battery recycling, charging time which mean some people are relucta...

All week long, we’re looking into 10 new terms and concepts that are certain to be on everyone’s lips in 2023! It’s nearly 11 months since Russia launched its invasion of Ukraine, and the war has reached somewhat of a stalemate. Many observers expected a swift Russian victory, no doubt including Vladimir Putin himself, but Ukrainian resistance proved fierce. Over the summer, Ukraine launched a cou...

If you’ve been to a climate demonstration in recent times, you may have noticed placards with a series of blue and red coloured stripes. Kind of like a barcode but in colour, with the shades varying from very light to very dark. You may have even seen them at political or sporting events, in the media, or on the cover of Greta Thunberg’s The Climate Book. This set of graphics are known as warming...

Today is Friday 13th, a day often seen as unlucky in Western superstition. Indeed, the tradition has become so ingrained that there’s even an associated phobia. It’s called, wait for it, paraskevidekatriaphobia!  Now, it might seem Friday 13th doesn’t come around very often, but most years actually have two and sometimes even three, depending on the calendar. 2022 was an anomaly with it occurring...

One of the many symptoms of Covid 19 was a loss of the sense of smell It is estimated that about two-thirds of patients experience loss of smell during acute COVID-19 and around  half of these will subsequently develop parosmia. Now researchers have been investigating what might cause this loss of smell and how to treat it. Loss of smell is known as anosmia. Parosmia is not a loss of smell but a s...

When talking about diversity and inclusion, the glass ceiling refers to an invisible barrier stopping those in minorities from obtaining upper-level workforce opportunities. The metaphor is most often used when talking about women. They may find their careers stagnating, unable to progress beyond a middle-management role, through no fault of their own. When it comes to senior positions, they are o...
